PWM
- 利用定时器控制产生占空比可变的 PWM 波 按K1,PWM值增加,则占空比减小,LED 灯渐暗。 按K2,PWM值减小,则占空比增加,LED 灯渐亮。 当PWM值增加到最大值或减小到最小值时,蜂鸣器将报警。-Have a timer to control the use of variable duty cycle PWM wave by K1, PWM values increase, then decrease the duty cycle, LED lights dimmin

- 数据采集系统: (1)采用定时中断和软件控制的方法,实现每隔N秒(N可设置)实现对模拟量的采集。 (2)根据预先设置的数值和采集的模拟量决定控制输出。如假设控制中心值为2.0V,当输入值超过2.0±0.2(V)时,模拟控制步进电机转:正偏差时反转,负偏差时正转;当输入值超过2.0±0.5(V)时,进行上、下限报警。 (3)对采集的值应进行数字滤波,如可一次采集10个值,去掉最大值、最小值,然后取平均值。 (4)实现8路采集,不同路的中心值及上、下限等参数可灵活设置。 -Dat

optimize-
- 键是一种标准零件,通常用来实现轴与轮毂之间的周向固定以传递转矩,有的还能实现轴上零件的轴向固定或轴向滑动导向。在键连接设计时,间的高度和宽度根据轴的直径d选取,而键长L则根据轴上零件轮毂宽度B而定,通常L=B-(5—10)mm。键的尺寸确定后,再进行强度校核。而为了保证绝对安全,键的尺寸取值往往都趋于保守,所选键的尺寸大。本程序采用优化设计方法,在满足强度要求的前提下求出键的最小结构尺寸,证明键宽b和键高h的取值可以小于标准值。-Key is a standard part, often use
Filtering-method-and-164-display
- 滤波法:相当于“中位值滤波法”+“算术平均滤波法”,连续采样N个数据,去掉一个最大值和一个最小值,然后计算N-2个数据的算 术平均值 N值的选取:3~14 优点:融合了两种滤波法的优点,对于偶然出现的脉冲性干扰,可消除由于脉冲干扰所引起的采样值偏差 缺点:测量速度较慢,和算术平均滤波法一样,比较浪费RAM 164显示:只需两个IO口即可驱动,节约IO脚 -Filtering method: method: the equivalent of " median filte

- 题目:输入三个整数x,y,z,请把这三个数由小到大输出。 1.程序分析:我们想办法把最小的数放到x上,先将x与y进行比较,如果x>y则将x与y的值进行交换, 然后再用x与z进行比较,如果x>z则将x与z的值进行交换,这样能使x最小。-Title: Enter three integers x, y, z, please put the three and a number of small to large output. 1. Program analysis:
